installer: prepend nix paths to shell config files instead of appending

Browse source 
Some distribution will stop evaluating the shell config file if
they are not running in an interactive shell. As we append the nix
paths to the end of the file, they will not be evaluated.

We better prepend the nix paths to the shell config files to be sure
that once nix is installed, nix path will be available in any shell.

Note that this is already the case for the detsys installer script for
a while: https://github.com/DeterminateSystems/nix-installer/pull/148
